Patent JP-S62215234-A (JP)
Title: Liquid crystal display device
Inventor: ARAI KAZUO
IPC: G09F9/35
Filed: 1986-03-15
Abstract: PURPOSE:To obtain a device which maintains high contrast even in case of using a high-order time-division driving system by specifying the angle of torsion of liquid crystal molecules of a liquid crystal composite body arranged between a couple of substrates and the relation between the elastic contrast in the torsion direction and bending direction of the liquid crystal composite body. CONSTITUTION:This liquid crystal display is constituted by arranging the liquid crystal composite body between the couple of substrates 1 and 2 which have orientation film respectively; and the angle alpha of torsion of liquid crystal molecules of the liquid crystal composite body arranged between the couple of substrates is 160-250 deg. and k33/k23>=3.0 holds for the elastic constant k22 in the torsion direction of the liquid crystal composite body and the elastic constant in the bending direction. When the angle alpha of torsion is <=160 deg., varia tion in the intensity of transmitted light to an applied voltage is slow and suffi cient contrast is not obtained during high-order time-division driving. When the angle 3a of torsion is >250 deg., the array of liquid crystal molecules is easily disordered during on-off switching to cause deterioration in display quality or slow down the response speed of on-off operation due to large bistable effect.

Title: Attenuator circuit
Inventor: NAGAMATSU SHUNICHI
IPC: H03H11/24
Filed: 1988-03-11
Abstract: PURPOSE:To control the attenuation value with a small control current and to reduce the impedance by adding a current supply means to each collector of a 1st differential pair of transistors to supply a constant current. CONSTITUTION:The constant current sources 20 and 21 are set between a power supply terminal 15 and each collector of the transistors TR Q1 and Q2 forming a differential amplifier 14. Then a constant current I is supplied to each collector of both TR Q1 and Q2 respectively. In such a way, the attenuation value can be controlled with a small control current IC and the impedance is also reduced with no problem by supplying the current I to each collector of a 1st differential pair of TR Q1 and Q2.

Title: Stereoscopic photographing device
Inventor: OTSUKA HIROYUKI
IPC: G03B35/08
Filed: 1990-03-07
Abstract: PURPOSE:To change a base length even when a prism is not used, to miniaturize a device and to contrive the reduction in weight by setting a pair of visual field lenses at a position where the optical axes of the lenses move in a right- and-left direction from the optical axis of this stereoscopic photographing optical system. CONSTITUTION:In the case of stereoscopically photographing an eye to be examined E, quick return mirrors 83 and 84 are respectively moved to the optical paths of the stereoscopic photographing optical systems 81 and 82 by pushing a shutter. The reflected luminous flux which reaches zoom lenses 55 and 56 is reflected on the mirrors 83 and 84 and reaches relay lenses 91 and 92 through lenses for stereoscopic photographing 85 and 86, the visual field lenses 87 and 88 and reflection mirrors 89 and 90, and the image of eyeground is formed on a film F. Since the lenses 87 and 88 are set on the inner side than the respective optical axes, they act as the prism, thereby bending the luminous flux inside and shortening the base length in the film F.

Title: Sliding door guide mechanism of sprash guard
Inventor: SUZUKI RYUJI
IPC: E05D15/06
Filed: 1987-03-14
Abstract: PURPOSE:To make the opening/closing operation of a sliding door smooth by providing a rail means in which a first wall face part and a reversely directed second wall face part are erected on a horizontal part, while installing a pair of roller means which rollably hold the horizontal part of said rail means in between on said sliding door. CONSTITUTION:A guide rail 32 is fixed to the inside of the lower panel 20 of a sprash guard via a bracket 30. And, a horizontal part 36 which exists between wall face parts 38, 34 are interposedly held by a pair of rollers 42, 46 which are installed on a sliding door 14. Thereby, even if the sliding door 14 is moved in the Y direction, either the roller 42 is brought into contact with the wall face part 34 or the roller 46 with the wall face part 38, without causing the delailment of the rollers 42, 46 off of the rail 32. Also, even if chips or machining liquid resulting from the machining of a workpiece may fall on the guide rail 32, these fall along the outer face of the wall face part 38 from the horizontal face part 36. Due to such a structure, the opening/closing operation of the sliding door 14 of the sprash guard can be smoothly carried out.

Title: Pop noise reduction circuit
Inventor: FUJIMOTO KEISUKE
IPC: H03G3/34
Filed: 1991-02-28
Abstract: PURPOSE:To surely eliminate a pop noise and to prevent malfunction from occurring by detecting the disconnection of a power switch at high speed, and applying mute to a signal. CONSTITUTION:This circuit is provided with a mute circuit 4 which applies the mute to an input audio signal SIG at need, a comparator 6 which compares two terminal voltages of the power switch POW and turns on a mute signal MUTE when the difference of them exceeds a constant value, and a speaker SP driven by a power IC 3. When potential at a point A goes less than that at a point B, a transistor T3 is turned on. and the mute signal MUTE is turned on. Since such condition is established immediately after the switch POW is turned off, the mute circuit 4 can be quickly operated. Also, since the voltage at the point A is equal to that at the point B by a ripple on an ACC when the switch POW is turned on, no malfunction of the mute circuit 4 can be prevented from occurring.

Title: Effective utilizing method of coal ash
Inventor: KOSHIDA TAKAHISA
IPC: F27D15/00
Filed: 1982-04-09
Abstract: PURPOSE:To stabilize melting converter slag by adding the coal ash produced by combustion of caol into the converter slag and decreasing the content of the free lime formed in the slag to a specified value or below. CONSTITUTION:The coal ash formed after combustion of coal is added in the form of powder into melting converter slag or is added thereto after molding into a granular shape to decrease the K value expressed by equation in the converter slag after the addition down to <=10.

The coal ash contains SiO2 and Al2O3 which are acidic components in large amt. as essential components. The m.p. thereof is as low as around 1,100 deg.C and the grain size thereof is small; therefore, if the coal ash is added to the melting converter slag, melts thoroughly and reacts well with the free lime, thereby decreasing the same.
